`-'The invention relates to improved `means `for loading and positioning a plurality of cores on 'a 'Winder shaft.

It 4has been customary to rewind na web of a given width into a plurality of rolls each of "lesser width by slitting the web as it is unwound 'from the parent roll and rewindin'g the plurality of strips onto a series of tubular, hollow cores which 'are 'disposed upon Aa rewinder shaft. if it is desired to form 'a plurality 'of rolls each 'having a Awidth of twelve ('12) inches from a web vsixty Y(60) inches wide, the web is slit into iive strips and wound onto five tubular cores disposed on lthe 'rewinder shaft. Heretofore, the tuloular lcores have o'een'placed in edge to edge abutting relationship on the rewinder `shaft -by han'd with the consequent loss of time and high labor costs.

It has been found desirable to use 'tubular icores having a length '-le'ss than the widths of the strips being wound thereon. For example, a strip twelve (12) inches Wide may satisfactorily be wound vupon 'a tubular core only lsix ,(6) inches long, result-ing in a saving of half the core material costs. The use of 'such short- 'ened cores, however, has been prohibitive commercially because of Ithe amount of time consumed in manually placing and accurately spacing the cores upon the rewinder shaft. The

shortened core shouldbe located centrally, widthwise, of the wound strip.

By means of our invention the tubular cores are quickly and easily 'positioned on the rewinder shaft in accurate spaced relationship with a minimum of time andeffort.

Various objects land advantages of the invention will he evident from the following description and drawings, wherein:

.Referring 'to rthe drawings, 'the apparatus ln,- cludes a hopper 'I0 comprising 1a front wall ISI., side walls l2., a .rear wall I3 and a sloping bot- Stom plate Ill., all preferably of sheet metal and suitably bolted or welded together. The sloping bottom plate ld extends from the 'rear wall `l`3 downwardly at yan angle of approximately 35. Within the .hopper `I`IJ 'the bottom plate "Il is out out or iormed so -that its .lowest extremity ity is spaced from the iront 'plate I1 a distance slightlyv greater than the diameter of .a core. The hopper III rests and is fastened on spaced channel supports f5 including angle members .li supporting the bottom plalte (i4. The hopper 'l0 is separated into a plurality of spaced core storage compartments or .magazines I l by Aa series of spaced, vertically disposed .plates 1B, preferably o'f sheet metal, bolted 'to -the front and 'rear walls 1i and 1.3. The core storage compartments 'l1 are slightly wider than 'the length of the tuloular cores .'Ill, which preferablyare of spirally wound carboard. The core storage magazines or compartments Il are spaced 'from each other a distance substantially equal vto 'the distance it is desired to space the cores 1'9 virom each other on a rewinder shaft 20. As shown in Figure 4, 'the rewinder shaft '20 having ha diameter D uis formed with a 'tapered end '2lil having a smaller diameter D" at its end. The hopper I0 is open at the top 'to permit the core storage compartments Il to be replenished. The 'front wall 1'l of Ithe hopper l0 has elongated, vertically disposed yslots 2l opening onto the `core storage compartments 'll in order that 'the operator may visually determine Vwhether or not the core `storage compartments Il require refilling.

Preferably, a plurality of rewinder shaft guides Sare fastened by bolts "3l to a vertically disposed plate 3'4 extending the width of "the hopper, lill. Vhs shown in Figure 6A, 'the plate 3l is supported in fixed ,position by .an L-shaped bar '321". which is supportedA a't its ends by. the channel supports l5. The bolts 31 secure together the .guides 3U, 'the .plate 3l and 'the bar 34".. The rewinder shaft guides '30 are located in the areas of 'the hopper :It intermediate the core storage 3 compartments Il and extend below the lower extremity of the front plate Il. A platev 32, preferably of sheet metal and of substantially the same height as the plate 34, is secured to the opposite faces of the guide bars 30 by the bolts 33. The plate 32 is disposed in abutting relation with the lower horizontal edge of the front plate II andV extends across the width of the hopper i9. The ends of the plate 32 are also suitably fastened to extensions I2 of the side walls i2. The bottom face of each guide 35 has formed therein a concave portion 39 having substantially the same radius of curvature as the rewinder shaft 29. The plates 32 and 34 Y are spaced apart a distance slightly greater than 'the incline of the bottom plate i4, the cores I9 will tend to fall into the passageways 35.

' A plurality of core stop mechanisms comprising holders 40 are bolted at 4I to the inside surface of the plate 32. As shown in Figure', a guide member 42 having secured to its lower end a core stop 43 is guided for vertical movement in an opening in the Vcore stop holder 40. The upper end only of the guide member 42 is threaded at 44 for engagement with an adjusting nutv 45. The guide member 42 has a pin 4B fixed thereto which in conjunction with a slot 41 formed in. the core stop holder 40 will prevent rotation of the guide member 42, and the core stop 43, when Ythe vertical position of the core stop 43 is adjusted by means of the adjusting nut 45. A compression spring '.48 encircles the guide member 42 intermediate the bottom of the core stop holder 40 and the top surface of the core stop 43. The lower face of the core stop 43 is adjusted'by means ofthe adjusting nut 45. The lower face of the core stop 43 is concavely formed at 49V onv a radius equal to the radius of the rewinder shaft 20. 'The'core stop 43 may be adjusted to the desired lowermost. position by means of the adjustable nut 45. The core stop 43 in its adjusted position, however, may be moved vertically upward `against the force exerted by the spring 48 when pressure is applied upward against the curved 'face 49 by the shaft 20. The guide member 42 will slide upwardly in the opening in the core stop holder 4G causing the nut 45 to be raised above the upper surface of the core stop holder '40. Y,When the upward pressure upon the curved face 49 is relieved, the spring 48 will -cause the core stop 43 to come down to the position limited by the location of nut 45 on the threaded portion 44 of the guide member 42. v

As shown in Figures 1, 4 and 5, the core stop mechanisms are located immediately adjacent and to the left of each passageway 35 leading from each of the core storage compartments I1. The action of the core stops 43 upon the cores I9 to` position them upon the rewinderV shaft 20 will be subsequently described.

' A trough 56, having aconcave face or thesame radius of curvature as the outer circumference of a core I9, has secured to its rear face, as by welding, a pluralityof spaced trough holder brackets 54. The other end of each trough holder bracket 54 comprises a collar 5I which encircles and is fixedly secured by a pin 55 (see Figure 6A) to a trough shaft 52 journaled in bearings 53 which are fixed in the supporting channels I5 at each end of the hopper I0. A channel member III) is mounted between the supporting channels I5 and extends the width of the hopper. The channel member IIll is disposed below and to the rear of trough shaft 52. A trough stop bracket III is secured to the channel member I I0 intermediate its ends, as by welding. .The face of the trough stop bracket III has secured thereto a pad II2 of resilient material such as rubber. The resilient material faced bracket III serves to limit the movement of the trough 50 when it is articulated to its downward or inoperative position where a trough holder bracket 54 contacts the resilient pad II2 (see Figure 3).

In order to assure that the cores I9 are each located on the exact desired segment of the re- Winder shaftv 20, it is preferred to provide a rewinder shaft stop II3 at one end of the trough 50. As shown in Figure 1, the rewinder shaft stop I I3 comprises an L-shaped bra-cket provided with a pad I I4 of resilient material such .as rubber secured to the vertical face of one portion of the bracket. The portion at right angles to the resilient covered Yportion has an opening therein through which a bolt II5 is passed. The bolt II5 also passes through a horizontally disposed slot IIS in a bar Ill which is suitably secured to the hopper supporting member I5. The position of the rewinder shaft stop II3 may be adjusted by sliding the stop in the slot IIS to the desired position and then tightening the stop in fixed position by means of a nut cooperable with the bolt II5 on the rear face of the slotted bar II'I. When the tapered. end 2.of the rewinder shaft 28 hits the Vresilient material covered face of the stop II3,. the precise positioning of the cores I9 on the rewinder shaft 20 is assured. n

One end of the shaft 52 has fixedly secured thereto a hand lever 56. By pressing downwardly upon the lever 56, in the position shown in Figures 1 and 3, the shaft '52 is rotated vcausing ther trough 50, through the holder brackets 54, to be swung upwardly to the -position shown in Figures2, 4 and 5. The trough 50 is locked in this upward, hopper engaging position` by means of a locking member 51 fixed for rotation with the shaft 52. The locking member 51 has a notch 58 which cooperates with the nose 59 of a lever arm Ell, part of a bell crank 6I fulcrumed on a pin 62 mounted on the support I5, and is part of a linkage to be subsequently described.

To prevent the cores I 9 from falling out of the passageways 35 when the trough 59 is retracted to the position shown in Figures 1 and 3, a trigger mechanism is provided. A trigger shaft 'I0 is journalled in a plurality of brackets 'II which are suitably fastened to the outer face of the plate 32. A series of triggers 12, cach having a core holding portion 13 substantially at a right angle to the trigger, are xedly mounted for rotation with the trigger shaft 1D. Preferably, the triggers 12 are located on the trigger shaft In so that a pair will engage a core I 9 in each passageway 35.

To rotate the trigger shaft l@ and bring the triggers 'I2 into or out of engagement with the cores I9, a triggerY actuating linkage is provided. This linkage includes a hand lever I4 pivotally mounted on the support I5 at l5. The lever 'I4 is connected to the lever arm S0 of the bell crank 6I by a connecting bar 'ISlby pins 'I'I and'l. The lever 'I4 is provided with an extension 'I4' upon which a counterweight II8 is mounted.

The counterWeightIIB Ypossesses an opening IISV message therethroughv through which the extension 'I4' passes. The counterweight may be moved to any desired position on the extension I4 and xed in such position by means of a set screw |20. The other arm 19 of the bell crank 6| is connected at 80 to one end of a bar 8|. The bar 8| is slotted at its other end where one end of an L-shaped lever arm 83 is received and engaged by a pin 82. The lever :arm 83 is fixed at its other end to the trigger shaft I by a suitable collar 84.

To assure that the cores .|9 are properly fed from the core storage compartments -I-'I .into the passageways 35, a pair o-f spaced agitators 90 are disposed in the lower portion of each core storage compartment Il through openings I4 formed in the sloping bottom plate I4. The vagitators 90 comprise Anotched wheels mounted on a shaft 9| for rotation in the direction of the arrow A. The shaft 9| is journalle'd in bearings 92 suitably supported in the .frame comprising the channel members l5. One :end -of the shaft 9| is connected Vfor rotation Ato Ja pulley and drive belt connected to .a suitable source of Vpower (not shown). The pulley and .belt are enclosed in a housing 93.

A receiving stand vis provided beneath the trough 50 and extends forward of the Ihopper I0. The receiving. stand comprises a downwardly sloping support |01 disposed `in a plane to 'permit the trough 501to be :swung down until a trough holder bracket 54 stops against the re-` silient faced trough holder :stop bracket III. A guide runner |02, formed with an upraised portion |03 at the end remote Afrom the hopper .|0, vis secured to each side of the -sloping support IOI. The guide runners |02 also :slope downwardly. As shown in Figure .1., a table I2| may be placed adjacent the .receiving :stand to :facilitate storing a plurality of rewinder shafts.

The apparatus .hereinbefore described is operated as follows. As shown in vFigures 2, 4 and 5 the trough 5|] is in :its upward core-supporting position and releasably locked .in such position by the notch 58 ofthe .locking member 51 and the nose 59 of the lever varm '60. In this position the trough 50 supports a :series of evenly spaced cores I9 which have fallen from the passageways 35 leading from each fof the .spaced core storage compartments the rotating agitators 90 aiding the feeding of the cores. The lowermost position of the core stop 43 .has been adjusted by the adjustable nut 45 so that its ooncave face 49 will be intermediate the diameter D of the rewinder shaft and the :smaller diameter D' of the shaft at the extremity of its tapered portion 20 when the rewinder shaft is inserted in the trough50.. In this :initial position the core retaining triggers l2 are retracted vso that their core holding portions .'13 are voutside of the passagewaysl 35. The .rewinder vshaft 'stop ||3 and the counterweight |.I'8 vare adj-usted and fixed in their desired positions.

A rewinder shaft 20, with the tapered portion 20' foremost, is inserted `in the opening formed by the trough 50 and the .hopper I0 and thr-ust in the direction of the arrow B (Figure-4) through the openings in the aligned hollow, tubular cores I9. The concave faces of (the guide bars 30 assure that the rewinder shaft 20 will be properly guided through the aligned, hollow, tubular cores I9. When the nose of the rewinder :shaft 20 hits the stop I I3, accurate positioning of the cores A I9 upon the Arewinder shaft is attained.` The eiect of thus thrusting the rewinder shaft Cil u' spaced ports are used opposite eachstorage come 20 is to cause the core ystops 43 to rise up on the tapered portion 20 of the rewinder shaft 20 onto the outer circumference of the shaft. The compression spring 48 will cause the concave face of each core stop 43 to firmly press against the shaft 20. The edge of each core rI9 bears against its respective core stop 43. The movement of the cores I9 beyond the core stops 43 is prevented while permitting the shaft 20 to slide through the central opening of each core. This action is best illustrated in Figures 4 and 6. In this manner., the desired number of tubular cores rare accurately positioned in spaced relationship on the shaft with but a single thrust of the shaft 20.

The operator then presses down on the hand lever 'I4 in the direction of the arrow El (Figure 2), which will cause the notch 58 of the vlooking member 51 to disengage from the .nose 59 of the lever arm 90 and the lever arm v56 to move upwardly in the direction of the arrow F. The weight of the rewinder shaft 20 will cause the trough 50 to swing down against the resilient material faces through stop bracket III and discharge the core loaded shaft 20 onto the inclined runners |02 where it rolls down to stop at the raised portions |03. As the locking member 51 is disengaged from lever arm 60, the trigger linkage is actuated to cause the core holding portions 13 of the triggers I2 to move into each passageway 35 and thereby prevent the stored cores I9 from falling out while the trough 50 is down. The core loaded .shaft 20 may then be placed on the table I2| for subsequent use in the rewinder. This stage of 'the operation is shown in Figures 1 and 3.

To ready the apparatus for another core loading and positioning operation it is simply necesi sary to press downwardly on the hand lever 56 from the position shown in Figure 3 to the position shown in Figure 2. This downward pressure will rotate the shaft v52 and locking member 51 clockwise. The counterweight IIS will 'cause the hand lever 'It to move upwardly thereby causing the nose 59 of the lever arm 60 to Aengage the notch 53 through the motion imparted to the connecting bar I0 by the hand lever 54. The mechanism has now assumed the position shown in Figure 2 with the trough 50 locked in its upward core loading position and the core holding triggers 12 retracted out of the passageways 35. Another series of cores I9 which have been fed by the sloping bottom I 4 and the `agitators 90 into their proper positions in the passageways 35 are ready to be loaded and positioned upon another rewinder shaft 20.

In lieu of the mechanical core stop mechanisms for loading the hollow, tubular cores upon a rewinder shaft in predetermined spaced relation, vacuum means may be utilized. As shown in Figures l, 2, 3, 4, 5, and G A, a pipe line |30 is set in and secured to the rear `'face of the trough 50 and extends the entire length thereof. The pipe line |30 is closed at one end thereof. The other end of the pipe line |30 is connected to vacuum tank and pump (not shown) by a flexible hose I 3| by means of 'a connection |32 between the pipe line and flexible hose. A plurality of spaced ports |33 extend through the trough 50 and connect the pipe line |30 with the inner concave face of the trough 50. The ports |33 are located in the trough 50 where they will be covered by the cores I9 which are fed from the ycore store compartments |-'I. Preferably, at least two partment. But'for the elimination of the -core stop mechanisms, andthe addition of a suitable resilient'liningY in trough 50 to form a proper seal for the vacuum, the apparatus described is otherwise the same.

With .the trough 50 in its upward position and the mechanism as shown in Figures 2, 4 and 5, a vacuum is applied to the pipeline |30. The cores I9 are pulled against a trough 50 by the reduction in air pressure through the ports l33. The application Yof the vacuum maintains the cores i9 in predetermined spaced relation and maintains the cores in such position, resisting lateral displacement, as a rewinder shaft is thrust through the aligned cores. After a rewinder shaft 2U is loaded, the vacuum is released. The trough e is retracted and the trigger mechanism actuated in the same manner as heretofore described.

The apparatus described is suitable for preparing for winding continuous sheet materials of waxed paper, toilet tissue, textiles, regenerated cellulose, metal foil, or any other flexible material. If lit is desired to wind the continuous sheet material upon cores having a square, hexagonal or other contour, the trough, core stop face, and rewinder shaft are given corresponding contours.

'It is within the scope of the invention to omit or retract the core stop mechanisms and dispose the cores on a rewinder shaft in abutting, edgeto-edge, rather than spaced relation. The core storage compartments will then be immediately adjacent each other Vrather than spaced as described. Also the guide bars 30 will be removed. In this manner the cores may be positioned on the rewinder shaft in edge-to-edge relationship with but a single movement of the rewinder shaft through rthe aligned cores. If desired, a single core stop mechanism may be positioned on the side of the apparatus remote from the side in which the rewinder shaft enters the aligned cores. This modification insures that all of the cores will remain on the shaft. This manner of positioning the cores upon a rewinder shaft in edge-to-edge abutting relationship results in a substantial saving of time and labor as compared with the present manual operation of slipping the cores individually onto the shaft.

Loading the cores onto the rewinder shaft in edge-to-edge, abutting relationship may also be accomplished by suitable disposition of the ports 133 where they will be covered by the abutting cores. The vacuum when applied will hold the cores against lateral displacement in the trough as a rewinder shaft is thrust through the aligned cores.

The present invention may be embodied in other specific forms without departing from the essential attributes thereof. It is desired that the present specific embodiment be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the aforegoing description to indicate the scope of the invention.
